Dimension 2EW Herbicide should be watered in within 7 days of application.
Dimension 2EW should not be applied within the drip line of any fruit trees. Also, the label does state that if your lawn is treated with Dimension 2EW, the grass clippings should not be left around the fruit trees.
Typically you want to mix your Dimension 2EW or any chemical with room temp water or something close to that. Cold water can often cause products to have trouble emulsifying into solution.
Dimension 2EW is a pre-emergent herbicide, so it is best applied before soil temperatures reach those that are optimal for the weeds you are targeting. This is generally before soil temperatures reach 55 degrees in the Spring. You should not apply when there is snow on the ground or temperatures are below freezing. In the Fall, you would want to apply before soil temperatures cool to those favorable for these weeds, usually below 70 degrees. We recommend contacting your local Cooperative Extension for the best recommendation on timing in your area.
Dimension 2EW which contains dithiopyr is labeled for use on carpetgrass.
Crabgrass seeds begin to germinate when soil temperatures reach 55 to 60 F and continue to germinate over several weeks from spring into summer. Pre-emergent herbicides such as Dimension 2EW normally should be applied in early to mid-April in southern Iowa, mid-April to May 1 in central Iowa and late April to early May in the northern portion of the state. Pre-emergent herbicides should be applied when the forsythia blossoms start dropping or when redbud trees begin to bloom. I found a great article here by Iowa State that further explains.
SnapShot 2.5 TG is not labeled to be used on lawns at all and would not be recommended. Dimension 2EW is our most popular pre-emergent herbicide for both grassy and broadleaf weeds and can be used on both St. Augustine and Centipede lawns. For Southern zones like FL, you would do a fall application by Oct 1st and for spring you would do a second application between February and March 15th at the latest. Re-applications and timing will depend specifically on what program you choose to use. Please review page 4 of the product label to determine the program that will best suit your needs. Tenacity or Atrazine would be good post emergent herbicides for your lawn type.
Dimension 2EW Herbicide is not labeled to be used in areas animals would graze so we cannot recommend it be used in the area. We actually do not have any pre-emergents for grassy weeds in pastures and would recommend contacting your local department of ag for assistance identifying the target weed and for a product recommendation. We can then see if we can get the product.
It is always best to perform any type of maintenance such as dethatching before you put down a pre-emergent like Dimension so that you do not interrupt the barrier and, therefore, get inconsistent weed control. You could potentially dethatch with a hand rake after watering in the Dimension application with at least 1/2 inch of water. Allow that watering to dry completely before dethatching.
According to the Dimension 2EW Herbicide product label, new sod/seed should not be applied for at least 3 months. Once the sod/seed has been put down, it needs to be established for at least 6 months before applying Dimension 2EW Herbicide again.
Dimension 2EW Herbicide is a pre-emergent herbicide that is labeled for spotted spurge. It will prevent the weed from germinating. If the weed is actively growing, we suggest selective post-emergent control. If you need a recommendation, please provide your desired turf species and size area. Thank you!
No, Dimension 2EW Herbicide will stay in the soil up to two years. It will be unsafe for the animals to graze until after the Dimension has left the soil on pastures.
Dimension 2EW Herbicide can be tank mixed with a variety of other herbicides and fertilizers. It is always recommended to do a test mix first to make sure whatever product you are wanting to use with the Dimension blends easily and does not cause clumping or any reaction that would cause your equipment to clog. Remember to follow the more restrictive label directions.

Dimension is best applied just before temperatures are suitable for weed seed germination. For crabgrass, this is when soil temperatures are about 55 degrees F. You will need to check your local weather forecast for a time when you will have several warm days in a row so that you can apply before that time for best results. You can usually check local soil temperatures online, too. You should not apply Dimension or other pre-emergents if the ground is frozen, if there is snow or ice on the ground, or if the ground is already saturated from rainfall.
